Problems solved by technology

However, due to the cleaning and treatment effect of this process, it cannot fully meet the requirements of process adhesion; and it uses a variety of cleaning agents and treatment agents to clean, with many processes and troublesome operation; the chemicals used are also very harmful to the environment. Large pollution is not conducive to the existing environmental protection, and there is a great threat to the health of operators; in addition, the use of chemical soaking is manual operation, and the overall usage cannot be controlled, resulting in serious waste of use, which affects Cost of production

Abstract

The invention discloses a method for treating the surface of a glass accessory. The method includes the first step of using alcohol to clean an adhesive region in the surface of the glass accessory and drying the adhesive region, the second step of using a plasma device to treat the surface of the glass accessory, wherein the input air pressure of the plasma device is 0.4-1.0Mpa, the plasma device can filter particles of over 0.3 micron, and the oil content at 20 DEG C is smaller than 0.1mg / m<3>, the third step of using a plasma outer flame to treat the adhesive region at the speed of 80-120mm / s, wherein a nozzle of a spray gun of the plasma device is 5-25mm away from the adhesive region, and the fourth step of enabling the adhesive region to be evenly coated with prime coat and then drying the adhesive region. According to the method, plasma treatment is adopted, it is guaranteed that the surface of the glass accessory will not be damaged, installation adhesion stress of the glass accessory is improved, the firmness and reliability of the glass accessory after installation are guaranteed, and the integral safety of an automobile is improved.

Description

technical field [0001] The invention relates to a surface treatment method for glass accessories. Background technique [0002] Glass accessories refer to the base supports required for the installation of rearview mirrors, sensor wipers, driving cameras and other equipment for automotive glass, as well as the positioning blocks used for gluing the edges of the automotive glass, and the support nails for fixing the automotive glass to the frame Columns, etc.; currently, in the existing glass accessories installation process, all accessories are cleaned with alcohol, acetone and other cleaning agents, soaked, finally dried, and then glued accordingly until the installation is completed . However, due to the cleaning and treatment effect of this process, it cannot fully meet the requirements of process adhesion; and it uses a variety of cleaning agents and treatment agents to clean, with many processes and troublesome operation; the chemicals used are also very harmful to the...
